Laptop Battery Tester

Active, pre-charge, constant current and constant voltage are the stages of charging mode. The initial charging mode depends on the battery voltage, so active and pre-charge don’t happen to every batteries.

Discharge:

Constant current discharge for double loads.

Test:

Testing time is 30 seconds and the purpose is to check both the charging and discharging performances.

Capacity Correction:

The battery capacity value in the battery management chip will different from the actual capacity after a battery goes through many recycling cycles. It will affect the use of the battery when the difference reaches a certain degree. Capacity correction is to deep discharge a battery and then fully charge, which will correct the capacity value in the battery management chip.

50% Capacity:

CD50%: charge firstly, and then discharge to 50% capacity

DC50%: discharge firstly, and then charge to 50% capacity
